Outline of Final Research Achievements

Spectra of complexes with an unstable molecule CS and rare gases have been observed and 3-dimensional intermolecular potentials were determined. We also observed spectra of CH2OO with water, that has attracted much attention in atmospheric chemistry in recent years. The structure of the complex was determined to be planar cyclic. We also observed a reaction product of CH2OO and water, hydroxymethyl-hydroperoxyde (HMHP), which is considered to be a key species for the reaction of CH2OO. Furthermore, complexes with Ar, CO, and N2 were also observed and determined their structures and discussed their intermolecular dynamics.
